8mm Mini Micro Stepper Motor 2 phase 18 degree step angle
Description
A stepper motor is a motor that converts electrical pulse signals into corresponding angular
displacement or linear displacement. They have multiple coils that are organized in groups called
"phases". By energizing each phase in sequence, the motor will rotate, one step at a time.
With a driver controlled stepping you can achieve very precise positioning and speed control. For
this reason, stepper motors are the motor of choice for many precision motion control
applications.

Application
Motor’s speed is determined by driving frequency, and it has nothing to do with load (unless it’s losing steps).
Due to high precision speed control of stepper motors, with a driver controlled stepping you can achieve very precise positioning and speed control. For this reason, stepper motors are the motor of choice for many precision motion control applications.
For linear stepper motors, they are widely used in:
Medical device
Camera equipment
Valve control system
Test instrument
3D printing
Textile machinery
Industrial control
Air conditioning
CNC machine
and so on
Customization service
Motor’s design can be adjusted based on customer’s requirement including:
Motor’s diameter: we have 6mm, 8mm, 10mm, 15mm and 20 mm diameter motor
Coil resistance/ rated voltage: coil resistance is adjustable, and with higher resistance, motor’s rated voltage is higher.
Bracket design/ lead screw length: if customer want the bracket to be longer/short, with special design such as mounting holes, it’s adjustable.
PCB + cables + connector: PCB’s design, cable length and connector pitch are all adjustable, they can be replaced into FPC if customers require.
Lead Time and Packaging Information
Lead time for samples:
Standard motors in stock: within 3 days
Standard motors not in stock: within 15 days
Customized products: About 25~30 days (based on complexity of customization)
Lead time for building a new mold: generally about 45 days
Lead time for mass production: based on order quantity
Packaging:
Samples are packed in foam sponge with a paper box, shipped by express
Mass production, motors are packed in corrugated cartons with transparent film outside. (shipping by air)
If shipped by sea, product will be packed on pallets
Shipping Method
On samples and air shipping, we use Fedex/TNT/UPS/DHL. (5~12 days for express service)
For sea shipping, we use our shipping agent, and ship from Shanghai port. (45~70 days for sea shipping)
FAQ
1.Are you a manufacturer?
Yes, we are a manufacture, and we produces mainly stepper motors.
2.Where is your factory location? Can we visit your factory?
Our factory is located in Changzhou, Jiangsu. Yes, you are very welcome to visit us.
3.Can you provide free samples?
No, we don’t provide free samples. Customers won’t treat free samples fairly.
4.Who pays for shipping cost? Can I use my shipping account?
Customers pay for shipping cost. We will quote you shipping cost.
If you think you have cheaper/more convenient shipping method, we can use you shipping account.
5.What’s you MOQ? Can I order one motor?
We don’t have MOQ, and you can order only one piece sample.
But we recommend you to order a little bit more, just in case the motor is damaged during your testing, and you can have a back-up.
6.We are developing a new project, do you provide customization service? Can we sign a NDA contract?
We have over 20 years of experience in stepper motor industry.
We have developed many projects, we can provide full set customization from design drawing to production.
We are confident we can give you few advice/suggestions for your stepper motor project.
If you are worrying about confidential issues, yes, we can sign a NDA contract.
7.Do you sell drivers? Do you produce them?
Yes, we do sell drivers. They are only suitable for temporary sample test, not suitable for mass production.
We do not produce drivers, we only produce stepper motors
